how to tell whether you have an AX-15 or a BA10/5 5spd trans

[JeepcoMJ]

the jeep transmissions in cherokees and comanches were 21 spline through mid 1990, with a few exceptions;

mid 1990 AW4 automatic transmission went from 21 spline input t-case to 23 spline

mid 1989 Ax15 was introduced, and the BA10/5 was phased out.

 

the AX15 will have a 23 spline output, so a 23 spline input on the t-case.

 

the Ba10/5 is a 21 spline output, thus the t-case is 21 spline input.

 

here is the BA10/5, and a link to info about it

here is the AX-15, and a link about it

if you are working on your trans, check your transmission before you buy anything. if you're wrong about which transmission you have... you will not be happy. the easiest way to tell which one it is is that the AX15 is larger, and it has a iron/cast mid-plate between the front and rear housings (it is located just in front of the shifter). the BA10/5 does not have that mid-plate

Couple more photos for comparison.

 

 

 

and here's a couple 2wd versions. AX-15 is on the left:

How about a pic from laying under the truck looking up with the tranny still installed... I'm going to see that more often than one removed and or from the side...

lol. i only think I can get one from my bro's truck, which has an ax15

[Pete M]

Look for the row of bolts running lengthwise along the bottom edge of the Peugeot. It looks just like the top of the Peugeot.

If you don't feel like crawling underneath but have access to the hole where the shifter sticks out, the BA 10/5 has 3 bolts on the shifter and the AX-15 has 4 bolts. The AX-5 also has 4 bolts (shifter may swap but I haven't tried it) If it's 4 cyl, most likely AX-5 unless a Dakota bell. etc was used during an upgrade.

which is better :dunno:

AX-15 > Wet noodles in jello > BA 10/5

Not sure why I didn't notice this before... but the AX-15 has a cast aluminum midplate. The AX-4/5 has a cast iron one.

so BA10/5=bad?

[Geonovast]

so BA10/5=bad?

 

Not necessarily. They make excellent boat anchors.

 

Seriously though, if they're in a DD and you're not too bad on it, you should be fine. My first 2 XJs had them, and I beat the crap out of them, and they never broke.

 

They're a lot like a D35. Some D35s do fine with 35" tires and are wheeled hard, and some break if you look at them wrong.

[Squeegy410]

I know i have a D44. on an 89 5 speed eliminator with a D44 would it be more likely a BA10/5 or an AX15? i don't have time to crawl around right now and its killing me lol

Rear axle has nothing to do with it, it's all dependent on when it was built. Early 89s got the pukey, later ones got the AX-15. No idea when the break was. Know the build date of your truck?

[Squeegy410]

nope. apparently I'm hoping late though ;) I know it has had a long life and a hard one. even if it is the pugeot its a good one :dunno:

[Squeegy410]

the excruciating part of this is that I'm in the library and can see my truck from the window but can't go out and look at it because ia hve to do math :doh:

[Geonovast]

They only other way I could help you is if you happen to know RPMs at a certain speed in 1st. All the gear ratios between them are the same, except for 1st.

[Squeegy410]

would a serial number tell you anything?

[Geonovast]

Serial number on what?

 

Probably not.

[Squeegy410]

the stuff in the door has all worn off so i can't tell what year it was in. all ive got is the number from the dash pad on the driver side :dunno:

[Geonovast]

Did you just run out there? Cause you could've simply glanced under the truck.... they're very easy to tell apart from the bottom.

[Squeegy410]

i have pictures on my camera which i have with me lol. i knew you would think that lol. i'm not that dumb :rotf:
